Abstract
Non-bond crosslinked macroporous thermally reversible hydrogels of poly-N-isopropylacrylamide were obtained by copolymerization with the crosslinking agent cyclic octaethylene glycol fumarate, a 29-membered ring, having a polymerizable double bond; threading of polymer chains into the macrocyclic ring being the cause for the crosslinking. These hydrogels showed a high swelling capacity in water which could be controlled by varying the molar ratio of monomer/crosslinking agent. They rapidly 'collapsed' at 33° and swelled back at low temperatures.
